Specification of Letters Patent.

Patented Sept. 9, 1913.

Application filed .Tilly 27, 1906. Serial No. 328,128.

To all whom may concern.'

Be it known that I, ARTHUR J. CUMNOCK, a citizen of the United States, and a resident of Rye, New York, have invented certain new and useful Improvements in Teb- Cutting Machines, of which the following is a specification.

My invention relates to a web cutting machine, particularly adapted to cut a tubular web intol pieces, which may of course be cut directly across the web, but which in practice are usually of broken contour to form parts of garments or similar articles.

In my Patent No. 829,098 granted August 21, 1900, I have shown a machine for cutting a tubular web, in which machine is provided a mandrel supported within the web for extending the same, said mandrel being provided with cutting blades on its opposite surface for coperating with movable cutting blades in the machine for severing the web. In my Patent No. 829,099, granted August 21, 1906, I have shown another tubular web cutting machine in which is also shown a mandrel supported entirely within the web for maintaining lateral tension therein. In both of these machines the opposite faces of the tubular web are separately cut, the web being in its original folds, that is, with the selvages which imite the two plies of the web remaining in their original position.

My present invention has for its object the folding of the web so as to bring these selvages on the faces of the web before the cutting operation, and preferably to bring such selvages in superposition, so that bilaterally symmetrical portions can be cutfrom the web, the central line of which shall correspond with the median line of one of the faces of the fabric rather than with a selvage, both plies of the web being cut together.

Further objects of the invention will a; pear in the specification and be pointed outin the claims.

In the drawings, Figure 1 is an illustrative view showing the tubular articles refolded into final form ready to be sewn together to form the finished article. Fig. 2 shows the web cut into tubular articles by the means provided in the present applicatio-n. Fig. 3 is a side elevation of a machine embodying my invention, with a portion of the frame removed for clearness of illustration. Fig. 4 is a top plan view of the same. Fig. 5 is an end elevation of the same. Fig. 6 represents in perspective a mandrel detached from the machine, with a portion of the web ready to pass thereover. Fig. 7 is a similar view of a modified form of mandrel. Figs. 8, 9 and 10 are views corresponding to Figs. 3, 4 and 5 respectively of a modified form of my device.

Referring to Figs. 3, 4, 5 and G of the drawings, 11 designates the body of the machine, from which rise four corner uprights 12. Mounted on shafts 13 adjacent the upper ends of the uprights 12 are grooved pulleys 14 adapted to support between them a mandrel 15, which, as shown, consists of an upper sector-shaped fiat portion 16, at the upper and wider end of which is mounted on each side a pair of small idlers 17, 1S, preferably having convex faces for engaging in the grooves of the pulleys 14. It will be seen that the width of the portion 16 at its upper end is such that the idlers 17 and 18 engage respectively above and below the horizontal diameter of the pulleys 14, so that the mandrel 15 is thereby supported and prevented from vertical movement in either direction, as well as from lateral movement. Extending laterally from, and in the present instance at a right angle with, the portion 16 are trianf gular blades 19, the lower ends 20 of which are united and are together of a width approximately equal to that of the upper end of the part 16. Mounted on shafts 21 below the shafts 13 are two large rolls 22, 23, one of the shafts 21 being connected with a source of power, not shown, for rotating the same. On the roll 22 is a sprocket wheel .24 connected by a sprocket chain 25 to a similar sprocket wheel 26 on a small shaft 27 supported on a suitable standard 28 on the. frame of the machine. The shaft 2?' carries a spur wheel 29 meshing with a similar spur wheel 30 on the shaft 21 of the roll 28. It is obvious that the effect of this mechanism is to cause the rolls to be simultaneously and equally rotated with their adjacent faces moving in the same direction, in the present instance, downward, as shown by the arrows in Fig. 3. It will also be seen that the lower end v2O of the mandrel 15 extends downwardly somewhat between the rolls 22 and 23 and parallel with the axis thereof. On the roll 23 vis shown `a plurality of blades 31, 32, of broken contour, and in the present instance adapted 'to cut from the tubular web 33 shirt bodies 34, such as are shown in Fig. 2 of the drawings. The blades 31 and 32 are adapted to cooperate with a stationary blade 35, vwhich is suitablysecured in a bracket or standard 36 mounted on the Eframe of the `ma cliine. The rolly 22 is provided lwith recesses37, 38 adapted to receive the blades 31,32 respectively. The faces of the vrolls 22 and 23 are, in tl'ie `present instance, formed with `diagonally disposed lines. These are preferably produced by securing on the faces of the roll sheets of rubber cloth v39 or Vthe like haif'in'g 'these [diagonal lines 40 formed therein. A reference to Fig. 4 of the drawings 'will clearly show :that these lines are so disposedasto maintain the lateral tension on a web passing between the 'rolls and preferably to slightly stretch Vit laterally, that is, to increase such lateral tension.

The operation lof the device is as follows: The lend 'df a tubular web 33, which itis desired to cutiinto pieces, usually of broken contour, 'and in the lpresent instance into shirt bodies, 'is lslipped over the vupper end ofthe mandrel 15, so that it passesbetween the idlers 17 and =18 and the grooved pulleys 1 4. nlt is understood that in this position the Aselvages 41 of the web are 'at vthe edges of its "faces 42, th'atis, the web is in its natural folds. The ywebis then' drawn down over the Vmandrel 15, by which it is folded'to bring its selvages 41 into superposition or together, iformin'gnew folds in the middle ofeach face 42ofthe web. The web "thus `folded is passed 4between the rollers 22 and 23, which act to press together 'the faces of Athe web in their 'foldedlpositiom and to maintain or slightly increase its lateral tension. The machine beingstaited, it is evident that the web will be continuously fed over the mandrel 15, will be Ifoldedto bring its s'elvages on the faces of the web, and in the present'instance in superposition, and'that the blades 31and on the roll 23 in cooperation with vthe blade 35 will act to 'cut 'simultaneously through both pliesv of the web, and form, in the presentinstanc'e, the shirtlbodies shown in Fig. 2 ofthe drawings, it being understood that the blades 31 are adapted to out the shoulder seam and arm scye portion at the'upperportion of the shirt body, `and the blade 32 adapted to cut the lower end of the skirt of the shirt, rounding olf its corners vas shown.

By referring to Fig. 1.I ofthe drawings, it will be vseenthat the tubular article 'after same has been cut'from the tubular web, as shown in Fig. 2,' can're'adily be refolded so as to bring the back and front of the shirt body in superposed relation and the tubular article will then be ready for the sewing or finishing operation. By folding the web as in the present device, both plies are cut `sim'ultaneously and exactly alike, so that the tubular article when refolded to its original folds, will present the appearance shown in Fig. 1. In boththese drawings the fronts ofthe shirts 'are 'designated by the numerals 43, and the backs by the numerals 44.

ln the form of 'mandrel shown in Fig. 7,

t-he blades y19 are replaced by bars 50, each of *which is pivoted at its upperend 51- land is 'guidedito move at a right angle with the sector 16 'between a pair of brackets 52. Near the lowerfendof each'of the'bars 50 is a spring 53, by which it is forced laterally outward fromthe portion 16. It is obvious that th'elowe'r corners 54 ofthe bars will act to fold the web just as the blade 20 does in the form of device shown in Fig.'6,"and that the operation of the device will 'not be changed by vthis alteration, except that the lateral tension on the web will be somewhat increased.

Figs. '8, 9 and `10 ofthe drawings show a preferred form of my folding and cutting device, in which the mandrel is dispensed with. The bed 11 and u'pri-ghts 12 will be 'as before described. Mounted'on a pair of cross bars 61 are bearings 62, in which rotate shafts 63, 64, on each of which is mounted a roll 65,66. y'Guides 67, shown vas bent rods, maybe provided above the adj acent faces of the *rolls 65, 66 for laterally guiding the web between them. Mounted in cross bai-S68 of the frame below the cross bars 61 'are vshafts 69, 70, each of which carries a roll71, 72 respectively, these .being similar to the rolls 22 and 23 shown in the form of'device first described. As a 'means of rotating the rolls 71, 72 i1 provide a short shaft 73 mounted'on va standar`d`74 on the bed of the machine, on which is a bevel-gear 75 meshing with a similar bevel gear 76 on the 'shaft 69. A sprocket wheel 77 also mounted onthe shaft 69 carries a sprocket ch'ai'n 7 8, which passes over a similar sprocket'wheel 7 9 mounted 'on a short shaft 8O supported on a'standard S1. The shaft 80 also carries a spur wheel 82, which meshes with a corresponding spur wheel S3 on the shaft 70. It will be understood that the arrangement of parts is such that the rolls 71, 72 are simultaneously and-equally rotated in opposite'direlctions with 'their adjacent faces traveling in the same direction, inthe present instance, downward, as -shown lby the ar'rowsin Fig. 8. vIt i's-sometimes preferable to rotate the upper rolls Y'65 and 66 in like manner, and for this purpose I provide on the shaft 7 a pulley S4, which-is connected by a'belt 85 with a p'ulley'86 onthe shaft shafts 63 and Ge respectively act to rotate the rolls 65, 66, as before described. lt is understood that the rolls 7l, 72 are preferably faced, as before, with sheets of rubber cloth 39 having diagonal lines 40 formed therein, these lines being disposed, as already described with reference to Fig. a of the drawings. @ne of the rolls, as 72, also carries cutting blades S9, the other roll, as 7l,

being formed with recesses 90 for receiving the same. For convenience of illustration, l have shown the blades 89 as adapted to cut the shirt bodies shown in Fig. 2 of the drawings` As an additional means of folding and creasing the new folds in the web 33 to be cut, l provide adjacent each end of the rolls Tl, T2 a pair of small idler rolls 91, the axes of which are in a plane approximately at a right angle with the edges of the web as these are fed between the rolls 71 and 72. In the present instance l have shown these small rolls 91 mounted on brackets 92 on a cross bar 93 suitably supported in the frame of the machine. The oL eration of this form of the device will be readily understood from an inspection of the drawings. Fig. S shows the web 33 as being fed between the rolls G5 and G its selvages 41 being in their normal position at the edges of the web. after the web passes between these rolls the middle line of each face is creased and passed first between the idler rollers 91 and then between the large rolls 7l and 72. lt will be seen that in the present instance the nes of these rolls Tl and 72 are at a right angle with the axes of the rolls and 66, so that the cloth will be folded with its original selvages superposed one upon the other. rllhe cutting operation is similar to that already described, the blades 89 coperating with a blade 35 mounted on a bracket lt is desirable that the blades 89 and 35 should not come in exact contact with each other so as to wear, and l prefer to set them about one-thousandth of an inch apart, which eifectually cuts the web passing between them, while preventing any undue wear upon the blades. For this purpose l have shown in Fig. l0 the blade 35 as provided with slots 9st, so that it may be vertically adjusted and held in position by bolts 95 secured in the standard 3G.

lt is obvious that many mechanical changes may be made in my device without departing from the spirit of the invention as set forth in the claims. Thus, c. f., the vertical arrangement of the machine shown is obviously a matter of convenience. lhen, therefore, l speak of the cutting rolls as being below or beneath the mandrel or the upper rolls between which the web is en- `gaged, it is obvious that l intend to include any position of these rolls in which they are adapted to receive the web and to re-fold and cut the same.
